Overview of I-39/90 and US 12/18 (Beltline) interchange project

The purpose of the I-39/90 and US 12/18 (Beltline) interchange project is to accommodate I-39/90 traffic levels with a focus on safety issues that affect Interstate travel through the US 12/18 interchange and ensure compatibility with the I-39/90 reconstruction project south of US 12/18 to the Illinois state line.

Proposed improvements include:

  • Realigning I-39/90 northbound with three lanes before and after the interchange and two lanes through the core of the Beltline interchange.
    • The I-39/90 northbound to US 12/18 westbound exit ramp will be reconstructed as a right-side exit.
  • A third lane will be added to I-39/90 southbound through the core of the Beltline Interchange.
    • A dedicated exit-only lane will be added to the I-39/90 southbound exit ramp to US 12/18 westbound.
  • Extension of the merge lanes from the I-39/90 exit ramps to US 12/18 eastbound.
